When the program is loaded, the head is provided a variable mirror, the variable can be changed dynamically. In this way, the absolute address can be easily allocated when the linker links. Prior to the link after compilation: numeral disposed at the head of the image file, the latter bin when referring to an address offset based on this reference (base address). There are two scenarios (for a minimum unit mirror that has been linked ) : ![]() o may generate " can be installed, dynamic management software " Description: According to the above procedure, using. And for the function, although its internal local variables are at runtime The address is not fixed, but since the program has been compiled by a fixed program is a deterministic event, C-SPY can be predicted based on the information in the file) ( IAR 's debugging system C-SPY will perform JLIINK online debugging based on the ELF file, because the file contains the absolute address of each obj in memory. Eventually generate executable ELF or bin etc. Use IAR linker generating step to the "relocatable objectfiles (eg: relocatable ELF).

Recently engaged contiki in IAR transplant work on, and finally completed the transplant, but the generated bin file exceeds the MCU 's Flash size, MCUFlash to 512K, generated bin file 747K, the start has been that file system is too much lead, and later I think there are many doubts, so I studied the compilation and linking process of the IAR project. ![]()
